<title>Xcode 6 code completion  </title>
<description>IOS,Xcode 

2014/11/14&lt;p&gt;&lt;br /&gt;&lt;/p&gt;
&lt;!-- PLACEAD --&gt;&lt;!-- BIG LEFT --&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;p&gt;Xcode has some great features. Honestly, it's been so long since I've done anything with Xcode that I don't know which were added with 6 and which were already there, so &lt;a href="https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_6_0.html"&gt;New Features in Xcode 6&lt;/a&gt; is the place for those who have been playing along up to now.&lt;/p&gt;
&lt;p&gt;Whenever it was added, the thing I love is code completion. That's probably turned on by default, but if it isn't, look in Preferences-&gt;Text Editing.  With that on, as you start to type, possible completions are offered.  What particularly impressed me is that it's not just IOS library functions that will pop up, but also functions and variables that you have added yourself. That makes keeping track of your code so much easier, especially if you use expressive names.&lt;/p&gt;
&lt;p&gt;Of course it's also more than useful with IOS functions. Do you really want to type out "UIViewControllerInteractiveTransitioning"?  That was one of the things that drove me a bit batty when I first delved into IOS programming. Those long function and class names are such a pain if you don't have code completion.&lt;/p&gt;
&lt;p&gt;Unfortunately, code completion breaks sometimes. It doesn't break outright; some of it keeps working, but when you are new to this as I am, the partial breakdown is actually worse because you may not be sure if it's not completing because it is broken or because you are asking for something that doesn't exist. The fix, however, is easy. Quit Xcode, and &lt;/p&gt;
&lt;p&gt;&lt;i&gt; rm -rf  ~/Library-&gt;Developer-&gt;Xcode-&gt;DeriveData &lt;/i&gt;&lt;/p&gt;

&lt;p&gt;Then restart Xcode and code completion should start working again.&lt;/p&gt;

<title>The Complete IOS 8 Course with Swift  </title>
<description>IOS,Xcode 

2014/11/13&lt;p&gt;&lt;br /&gt;&lt;/p&gt;

&lt;!-- PLACEAD --&gt;&lt;!-- BIG LEFT --&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;p&gt;I pretty much gave up on IOS development. I had bought stacks of books and found plenty of on-line resources, but i ended up &lt;a href="http://aplawrence.com/MacOSX/ipad-development-frustration.html"&gt;frustrated and confused&lt;/a&gt;.  Even though I have some definite things I'd like to do, it was all too much and I quit.&lt;/p&gt;

&lt;p&gt;Recently I took a chance on &lt;a href="http://bitfountain.io/course/complete-ios8/"&gt;The Complete IOS 8 Course with Swift&lt;/a&gt;.  Pay no attention to the $499 price on that page; Google for it and you'll find it as inexpensively as $50.  I paid $75 for it and the IOS 7 course together.&lt;/p&gt;

&lt;p&gt;At $50 or so, I'd definitely recommend it. The course itself is well done, they do correct errors and there is also an active 
&lt;a href="http://community.bitfountain.io/"&gt;discussion community&lt;/a&gt; where you can find help from other users and the course developers. I do find that some questions get lost and ignored, but most of mine have been quickly answered.&lt;/p&gt;

&lt;p&gt;Is it enough to make me comfortable with IOS programming?  I really don't know yet. I'm not done with the course yet, and although there have been some development exercises that I was able to do, the real test will be when I dive into something new entirely by myself.  A bit gun shy from my previous muddled confusion, I don't feel like getting back up on that horse quite yet, but hope to soon and of course will report my struggles here.&lt;/p&gt;
&lt;p&gt;One thing to be very aware of is that Xcode 6 has its own peccadilloes. I'll talk about that some more tomorrow.&lt;/p&gt;

<title>Siri gets confused  </title>
<description>IOS,XCode 

2014/11/12&lt;p&gt;&lt;br /&gt;&lt;/p&gt;

&lt;p&gt;I dragged my wife into the world of smartphones on her &lt;a href="http://www.bubblews.com/news/9371157-my-wife-finally-gets-a-smart-phone"&gt;68th birthday&lt;/a&gt;. Actually, she didn't resist all that much, but it certainly was a long time coming.&lt;/p&gt;
&lt;p&gt;I knew that she'd like Siri, and especially so for calling people and sending texts. Texts is the method our youngest daughter prefers when it is too urgent for email.  Not wanting to bother her, I had my wife practice with me and we immediately ran into a problem: Siri couldn't text me.&lt;/p&gt;
&lt;p&gt;A quick look told me why: My name was in her phone seven times, some using the same number and some not.  Some were entered as "mobile", but most of them were marked as "other".  All of these had been transferred from her old phone; some of the duplicates came from that transfer, but most were just her adding me in again and again.  Her sister was there ten times and certain businesses (like a local nursery) appeared three or four times - no wonder Siri was confused!&lt;/p&gt;
&lt;p&gt;I spend a half hour this morning cleaning out her contacts and merging the ones where home and cell had neen entered separately. I tested texting and calling with Siri several times; it should be ready for my wife now.&lt;/p&gt;

<title>Kerio Control 8.4  </title>
<description>Control,Kerio,Networking 

2014/11/10&lt;p&gt;&lt;br /&gt;&lt;/p&gt;
&lt;!-- PLACEAD --&gt;&lt;!-- BIG LEFT --&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;p&gt;Kerio Control 8.4 adds some interesting features.  The first is the ability to filter https traffic, which obviously can only be done by the firewall effectively proxying your https requests and presenting its SSL certificate to the other site. As that isn't going to always work, Control also lets you exclude specific sites and specific internal users from https filtering. See &lt;a href="http://kb.kerio.com/product/kerio-control/content-filtering/filtering-https-connections-1651.html"&gt;Filtering HTTPS connections&lt;/a&gt; at Kerio's KB site.&lt;/p&gt;
&lt;p&gt;We now have a RADIUS server capability, which eliminates the need to have separate passwords for connected WiFi networks: &lt;a href="http://kb.kerio.com/product/kerio-control/server-configuration-kerio-control/using-radius-server-in-kerio-control-1648.html"&gt;Using RADIUS server in Kerio Control&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;IPV6 can now be specified as the target of a traffic rule, which means that a rule can be specific to that traffic.&lt;/p&gt;
&lt;p&gt;The last feature is the Guest Network. The typical use for this would be guest wifi.  Interfaces labeled as Guest have a special feature in that users there are not counted toward licenses. That means that the Guest Network could also be used to wire a classroom, lunchroom or whatever. Guest users do not pass through the Kerio Web Filter, but are otherwise fully secured.  See &lt;a href="http://kb.kerio.com/product/kerio-control/server-configuration-kerio-control/configuring-guest-network-1654.html"&gt;Configuring guest network&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;It's easy to try out Kerio Control by &lt;a href="http://www.kerio.com/support/kerio-control"&gt;downloading a free trial&lt;/a&gt;. I also have the hardware appliance version available for demo trial if that would better suit your needs.&lt;/p&gt;

<title>Amazon Echo  </title>
<description>Networking 

2014/11/09&lt;p&gt;&lt;br /&gt;&lt;/p&gt;

&lt;p&gt;I've mentioned Amazon Echo to a few people and had a wide range of reactions. Some are mildly intrigued as I am.  Many other insist that their smart phone does the same thing, although really that isn't quite true.  Your computer probably could function in a similar way, but it hasn't quite got it down either.&lt;/p&gt;
&lt;p&gt;What distinguishes Echo is two things: one is the array of microphones designed to pick up your voice without being close or shouting. The other is that this is not my smart phone or my wife's smart phone. It would be OUR Alexa, the helpful little bot that is sitting there waiting for us to need something, just like in the promotional video.&lt;/p&gt;
&lt;p&gt;&lt;iframe width="320" height="180" src="//www.youtube.com/embed/KkOCeAtKHIc" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;&lt;/p&gt;
&lt;p&gt;We fire up Google multiple times per day now. We jot down notes, reminders, shopping lists. We don't listen to music, but I do listen to NPR. I could easily see us using something like this and liking it.&lt;/p&gt;
&lt;p&gt;I'm not sure I'd like it enough at that price ($199), though.  We are already Prime members, so it would only be $99 for us, but I'm not sure I see that much value.  Thirty bucks, sure, no brainer, because if it didn't work all that well, it would have to be worth that much.&lt;/p&gt;
&lt;p&gt;Well, I did request an invitation.  I might just buy it and see.&lt;/p&gt;

&lt;!-- PLACEAD --&gt;&lt;!-- BIG LEFT --&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;p&gt;Our summer vacation spot offers free wireless DSL. Most of the time that is sufficient for our needs and when it isn't, I hot spot off my 4G phone. That's not free, of course, so I prefer to use the DSL.&lt;/p&gt;
&lt;p&gt;There is a problem though. The DSL hot spot is about 800 feet from us and in between are large metal boxes that our neighbors live in. They may think of those boxes as RV's or camping trailers, but I think of them as signal blockers. The combination of distance and those metal boxes can make for a spotty and unreliable signal.&lt;/p&gt;
&lt;p&gt;I found a reasonably inexpensive &lt;a href="http://www.amazon.com/exec/obidos/ASIN/B003YIFHJY/aplawrencescouni"&gt;High Gain USB Wireless G / N Long-Range WiFi Network Adapter&lt;/a&gt; at Amazon. I chose this one because they had Mac drivers as well as Windows.&lt;/p&gt;
&lt;p&gt;Installation was simple. I found I needed USB 3.0 port and an updated Macintosh driver from their support. My older Mac Mini only has one 3.0 port, so it is important to plug into that.&lt;/p&gt;
&lt;p&gt;Physically, I located this near a  window and as high as possible. I used the provided clip and used it with a beer carton  as I had nothing else handy. They did provide a suction cup mount that could have put it right on the window, but in my location that's in direct sun and it got VERY hot. &lt;/p&gt;
&lt;div style="text-align:center"&gt;

&lt;p&gt;&lt;img src="http://aplawrence.com/images/Antenna_Location.jpg" height="514" width="485" alt="Antenna Location" title="Antenna Location " /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;

&lt;/div&gt;
&lt;p&gt;Don't forget to turn your normal WiFi OFF. I found that I get a stronger signal and more reliable connection. However, it is still shared DSL, so it's not suitable for watching video. For my use (web and email), it's fine and much improved by this antenna.&lt;/p&gt;
&lt;div style="text-align:center"&gt;

&lt;p&gt;&lt;img src="http://aplawrence.com/images/Wireless_Utility.jpg" height="300" width="429" alt="Antenna Location" title="Antenna Location " /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;

&lt;/div&gt;
&lt;p&gt;At times, particularly after the computer has slept, I find that the wireless utility will show a good connection but I cannot access any sites. I've found that if I reaccess the Hot Spot welcome page, everything starts working. I bookmarked that page to make that easier.&lt;/p&gt;
&lt;div style="text-align:center"&gt;
&lt;p&gt;&lt;img src="http://aplawrence.com/images/HotSpot_Welcome.jpg" height="129" width="508" alt="Antenna Location" title="Antenna Location " /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;
&lt;/div&gt;
&lt;p&gt;This certainly has improved my wireless access.&lt;/p&gt;

<description>Connect,Kerio,Troubleshooting 

2014/01/01&lt;p&gt;&lt;br /&gt;&lt;/p&gt;

&lt;!-- PLACEAD --&gt;&lt;!-- BIG LEFT --&gt;
&lt;p&gt;You might think that with over 100 Kerio customers I'd be fairly busy with support calls. In fact, I get so few that's it's hard to pull together a decent length article. Once in a while I'll have something that confuses everyone thoroughly, and I do like to document those, but mostly I'm not that busy with Kerio support.&lt;/p&gt;
&lt;p&gt;I've decided to start documenting the past month's calls though because it helps me remember things myself. That's one of the problems I do have: often even simple fixes come up so rarely that I may have trouble remembering.  This documentation may help me and any users who stumble across it.&lt;/p&gt;
&lt;h3&gt;Missing Kerio Connect Panel/Ribbon&lt;/h3&gt;
&lt;p&gt;Right around Xmas I had a customer who wanted to set her "on vacation" status in Outlook.  "That's easy", I said, "it's in the Kerio Panel" (see &lt;a href="http://kb.kerio.com/product/kerio-connect/email-clients/kerio-outlook-connector/how-do-i-set-out-of-office-443.html"&gt;How do I set out of office?&lt;/a&gt;).  She replied that she had no Kerio Connect ribbon or tab.&lt;/p&gt;
&lt;p&gt;Oops. I'd seen that before, but couldn't remember the cause until I dug through a bunch of old email.  I sent this picture to explain what was wrong:&lt;/p&gt;
&lt;div style="text-align:center"&gt;

&lt;p&gt;&lt;a href="http://aplawrence.com/cgi-bin/showpic.pl?image=kerio_addins_lg.jpg&amp;amp;mytitle=Manage%20Addins%20for%20disabled%20Kerio%20Ribbon&amp;amp;returnpage=Kerio/trouble_shooting201401.html&amp;amp;returntitle=Kerio%20Troubleshooting%20January%202014"&gt;&lt;img src="http://aplawrence.com/images/kerio_addins.jpg" alt="Manage Addins for disabled Kerio Ribbon" title="Manage Addins for disabled Kerio Ribbon (click for larger view)" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;

&lt;/div&gt;
&lt;p&gt;Something or something had disabled the Kerio Outlook Connector User Interface addin. As I have seen that twice now, and I don't think the users did that themselves, this is apparently something that can happen by itself.&lt;/p&gt;
&lt;h3&gt;Disable Webmail "Integration with Windows" prompt&lt;/h3&gt;
&lt;p&gt;A customer wanted to disable this prompt.  He did not explain why other than to mention "for mobile users", so I suggested using &lt;a href="http://aplawrence.com/Kerio/user_access.html"&gt;access policies&lt;/a&gt; instead, but that's not what he wanted.  I think he should still do that if he's trying to stop mobile users from accessing their business email, because disabling the prompt wouldn't stop the users from setting up email manually, but he insisted.&lt;/p&gt;
&lt;p&gt;That presents a problem. First, any upgrade will wipe out any changes he might make. Second, Kerio is very uninterested in providing any assistance with modifying their code.  I told him that, but said I would open a ticket in spite of my expectation that we'd get nothing useful back.&lt;/p&gt;
&lt;p&gt;As I thought, we got a friendly response that said pretty much what I had already told him.  In the meantime, the customer himself reported back that he had found the responsible file: he says it is in (kerio)/translation/webmail/en.deg  at line 285 to 290.  Again, I don't recommend doing this, but there it is.&lt;/p&gt;
&lt;h3&gt;Calendar permissions after domain change&lt;/h3&gt;
&lt;p&gt;This is a bit nasty.  I'd call it a bug. Kerio documents it in one sentence in their instructions for &lt;a href="http://kb.kerio.com/product/kerio-connect/server-configuration/domains/renaming-domains-in-kerio-connect-1122.html"&gt;Renaming domains in Kerio Connect&lt;/a&gt;.  The relevant sentence is this:&lt;/p&gt;
&lt;pre&gt;
Any calendar events created before renaming will not be available for editing
or removing after application of the new name.
&lt;/pre&gt;
&lt;p&gt;That means what it says. The events will still be there to annoy you if they are repeating events, but you won't be able to edit or remove them from within Webmail or Outlook.  You'd need to remove them outside at the operating system level.  In an email, Kerio support added:&lt;/p&gt;
&lt;blockquote&gt;
They should have removed those events before the rename took place, but if it's already done, they'd need to remove these manually at the filesystem level and let the indexes rebuild and probably also re-create the profiles in their clients (some clients may still have this cached).
&lt;/blockquote&gt;

&lt;hr /&gt;
&lt;p&gt;Other than things that were outside of Kerio itself (hardware and network issues), that was pretty much it for December. I have a couple of small issues I am still working with Kerio support; we'll cover those next month.&lt;/p&gt;

<title>Understanding Kerio Control Content Filtering  </title>
<description>Control,Kerio 

2013/12/18&lt;p&gt;&lt;br /&gt;&lt;/p&gt;

&lt;!-- PLACEAD --&gt;&lt;!-- BIG LEFT --&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;p&gt;This article was written for Kerio Control version 8.2.1.   Concepts expressed here may or may not apply to earlier or later versions.&lt;/p&gt;
&lt;p&gt;I find that Control Content and Web Filter are more confusing for my customers than any other part of Control.  After doing some testing, I think I understand why and can offer some advice that might make it easier.&lt;/p&gt;
&lt;p&gt;BE AWARE OF BROWSER CACHING WHEN TESTING! You can easily mistakenly think that your rule did not work if your browser has cached the page you are testing.&lt;/p&gt;
&lt;h2&gt;HTTP Rule&lt;/h2&gt;
&lt;p&gt;First, let's look at a simple deny rule.  You just want to deny access to foobar.com:&lt;/p&gt;
&lt;div style="text-align:center"&gt;
&lt;p&gt;&lt;a href="http://aplawrence.com/cgi-bin/showpic.pl?image=control_urls_simple_lg.jpg&amp;amp;mytitle=Simple%20Control%20Deny%20Rule&amp;amp;returnpage=Kerio/user_access.html&amp;amp;returntitle=Understanding%20Kerio%20Control%20Content%20Filtering"&gt;&lt;img src="http://aplawrence.com/images/control_urls_simple.jpg" alt="Simple Control Deny Rule" title="Simple Control Deny Rule (click for larger view)" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;
&lt;/div&gt;
&lt;p&gt;That rule will affect "foobar.com", "www.foobar.com" and "whatever.foobar.com/whatever/hello.html".   You do NOT need to use wildcards (*.foobar.com/*).  You CAN use wildcards, for example if you wanted to restrict to the top level of the domain with "foobar.com/*/*".  That would allow allow "www.foobar.com/whatever.html" but not "www.foobar.com/inside/whatever.html".&lt;/p&gt;
&lt;p&gt;That would be an extremely unusual case, though, so the general case is that you do NOT need wildcards in HTTP URL rules.&lt;/p&gt;
&lt;h2&gt;Regular expressions&lt;/h2&gt;
&lt;p&gt;You can also elect to use Perl regexes.  That would be even more unusual.&lt;/p&gt;


&lt;div style="text-align:center"&gt;

&lt;p&gt;&lt;a href="http://aplawrence.com/cgi-bin/showpic.pl?image=control_urls_regex_lg.jpg&amp;amp;mytitle=Simple%20Control%20Regex%20Rule&amp;amp;returnpage=Kerio/user_access.html&amp;amp;returntitle=Understanding%20Kerio%20Control%20Content%20Filtering"&gt;&lt;img src="http://aplawrence.com/images/control_urls_regex.jpg" alt="Simple Control Regex Rule" title="Simple Control Regex Rule (click for larger view)" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;

&lt;/div&gt;
&lt;p&gt;That regex, if used in a Deny rule, would stop you from going to anything in aplawrence.com/Linux, aplawrence.com/Unix (but not Unixart) as well as anything under MacOSX here.  Obviously regular expressions are for very unusual cases also.&lt;/p&gt;
&lt;h2&gt;Hostname Across All Protocols&lt;/h2&gt;
&lt;p&gt;That leaves us with "Hostname across all protocols".  That would block URL's like "ftp://ftp.somesite,com" (which would NOT be blocked by an HTTP rule), but it does not block command line ftp access.&lt;/p&gt;

&lt;p&gt;The Control manual gives an example of using that for Facebook and explains:&lt;/p&gt;
&lt;pre&gt;
Kerio Control sends DNS query and ensures that all IP addresses used 
by Facebook will be identified.
&lt;/pre&gt;
&lt;p&gt;I think what they mean is that if you use an ip address, Control will do a reverse lookup to see if it comes back with a host name that matches a rule.  I have not been able to test that, though.&lt;/p&gt;
&lt;h2&gt;Kerio Web Filter&lt;/h2&gt;
&lt;p&gt;The confusion here comes when a page is being blocked and needs to be whitelisted.  There are two ways to do this.  One is to add it to the Kerio Web Filter Whitelist:&lt;/p&gt;
&lt;div style="text-align:center"&gt;

&lt;p&gt;&lt;a href="http://aplawrence.com/cgi-bin/showpic.pl?image=control_urls_kwf_lg.jpg&amp;amp;mytitle=Using%20the%20KWF%20whitelist&amp;amp;returnpage=Kerio/control_urls.html&amp;amp;returntitle=Understanding%20Kerio%20Control%20Content%20Filtering"&gt;&lt;img src="http://aplawrence.com/images/control_urls_kwf.jpg" alt="Using the KWF whitelist" title="Using the KWF whitelist (click for larger view)" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;

&lt;/div&gt;
&lt;p&gt;If you do that, you MUST use wildcards: *.xyz.com/*&lt;/p&gt;
&lt;p&gt;However, you can add an ALLOW rule above the KWF rule and simply use xyz.com. The smart way to do that would be to have a "Whitelist" URL Group and add to that.&lt;/p&gt;
&lt;p&gt;This can obviously cause confusion - I'd suggest using one way and sticking to it.&lt;/p&gt;
&lt;p&gt;Kerio Support offered this:&lt;/p&gt;
&lt;blockquote&gt;
The option Hostname across all protocols is more difficult than the reverse proxy. For SSL it reads the certificate to get hostnames. So this option is a combination of previous SSL filtering option and reverse DNS lookup for the FTP filtering (you cannot filter FTP based on URL, as final request is IP based, that's why the reverse DNS lookup is made as well).
&lt;br /&gt;&lt;br /&gt;
New WebFilter Categories are also improved. One part of it is the DNS based service known as the Kerio Web Filter. The new part is the IDS detection of specific protocols, which can be used for further filtering. It means that for certain services you do not have to identify the port, but there is general inspection which can identify the communication type automatically and apply appropriate filtering module.
&lt;br /&gt;&lt;br /&gt;
This is a lot of modules put together hence the confusion in settings and it is a reason why each part accepts slightly different format. Some rules can be defined by regexp, while some of these cannot (eg. FTP, and HTTPS filtering where only the hostname part is present). Most of this confusion comes from a fact you mix the HTTP filtering (where you need to filter URLs) and FTP (which is in fact IP based filtering where regexp has no effect).
